(88) New Feature (12/22/04/JPR): The
user is now warned if an attempt is made to generate a "clipped" model in which
the clipping surface does not have the same dimensions as the grids that are
being clipped.

(87) New Feature (12/22/04/JPR): The
Geological-Utilities / Map / Multivariate-Maps / Pie-Chart-Map program now
includes options for plotting horizontal or vertical labels.

(85) New Feature (12/16/04/JPR): A new program
called "Append" has been added to the Grafix / 2-D Utilities menu. This
program is used to combine two-dimensional diagrams outside of the RockPlot/2D
program. It also provides a means for combining diagrams within the RCL
(RockWare Command Language).

(84) New Feature (12/16/04/JPR): The
Geological-Utilities / Grid / Grids->Fence program now includes a block of
options for plotting a reference "cage" around the diagram.

(83) New Feature (12/15/04/JPR): The
Geological-Utilities / Grid / Grids->3D-Stack program now includes a block of
options for plotting a reference "perimeter" around each grid layer.

The perimeter will be plotted as colored tubes. The user
may control the color and radius (as a percentage of the project size).

These perimeters are especially useful if the portions of the
grid will be rendered transparently (i.e. using the RockPlot/3D filtering
options).

(82) New Feature (12/15/04/JPR): The
Geological-Utilities / Grid / Grids->3D-Stack program now includes a block of
options for plotting a reference "cage" around the diagram.

(81) Bug Fix (12/11/04/MIW): Bitmaps within
striplogs are now properly clipped (assuming of course, that the clipping option
has been activated).

(79) Bug Fix (12/10/04/MIW): The program now
properly keeps track of multiple instances of the RockPlot/2D program (i.e. the
proper index is now displayed within the main RockWorks Window menu.

(78) Bug Fix (12/10/04/MIW): The "Create Separate
Location Map" option within the various Borehole Manager Section programs now
works correctly. The previous version would produce a distorted map.

(75) Bug Fix (12/10/04/MIW): The Borehole-Manager /
Stratigraphy / Fractures / Surface-Map program can now generate a 3-dimensional
diagram. The previous version would only plot two-dimensional maps.

(74) Bug Fix (12/10/04/MIW): The Borehole-Manager /
Fractures / Surface-Map program can now generate a 3-dimensional diagram.
The previous version would only plot two-dimensional maps.

(73) Bug Fix (12/09/04/JPR): The GridList.atd
sample file has been updated to reflect the renaming of the "Vadose Zone" to
"Overburden".

(72) New Feature (12/08/04/JPR): The solid modeling
menu now includes a new section titled "Maximum Distance Filter".

This new option is used to automatically assign a value to nodes
that are more than a user-defined distance from a control point, regardless of
the modeling algorithm.

Cutoff Distance: Nodes that are beyond this
distance from a control point will be assign to the following value.
Note: The cutoff distance is expressed as a percentage of the overall
project size (i.e. the distance from the lower southwest corner to the upper
northeast corner).

Replacement Value: Nodes that are beyond the
cutoff distance from a control point will be set to this value.

(71) New Feature (12/08/04/JPR): The File / Import
/ Into Borehole Manager / Excel (XLS) program now includes an option for
multiplying the depths by a user-defined conversion factor. This allows
user to change units during the import (e.g. feet to meters or vice-versa).

(67) New Feature (12/05/04/JPR): A new option
titled "Show Filter Results" has been added to the following Borehole Manager
menus that involve solid modeling.;

Lithology

I-Data

P-Data

This option will show the results of the range filtering,
duplicate point filtering, and/or stratabound clipping before the model is
generated.

(66) New Feature (12/05/04/JPR): A new option
titled "Remove Duplicate Points" has been added to the following Borehole
Manager menus that involve solid modeling.;

Lithology

I-Data

P-Data

This option will remove points that have already been defined
(i.e. the same xyz coordinates).

(65) New Feature (12/04/04/JPR): The
Geological-Utilities / Planes / StereoNet program can now be run via the RCL
(RockWorks Command Language). The RCL command for this option is "STEREO".

(64) Improvements (12/03/04/JPR): The
Geological-Utilities / Map / Multivariate-Maps / Starburst Map program now
includes and option for selecting horizontal or radial labels.

(63) Improvements (12/03/04/JPR): The
Geological-Utilities / Map / Multivariate-Maps / Spider Map program now includes
and option for selecting horizontal or radial labels.

(63) Improvements (12/02/04/JPR): The
Geological-Utilities / Linears / Rose program now includes a menu option for
plotting radial or horizontal ray labels (the previous version was limited to
radial labels).

This new capability is more comprehensible to non-technical
audiences who have a difficult time reading non-horizontal text.

(62) Improvements (12/02/04/JPR): The following
changes have been made to the Geological-Utilities / Linears / Rose program;

The Rays/Labels/Offset setting has been removed. The
program now has enough "smarts" to figure out how to position a label if the
font size is changed.

(60) Bug Fix (12/02/04/JPR): The Borehole Manager /
Striplogs / Multi-Log-Profile program now plots the special patterns and
associated text correctly. The previous version would omit these items.

(59) Bug Fix (12/02/04/JPR): The Borehole Manager /
Stratigraphy / Section / Straight / Plot-Logs option now works correctly.
The previous version would incorrectly place the logs if the Plot-Logs option
was turned on.

(57) Bug Fix (11/30/04/MIW): The ReportWorks
program no longer generates an error message if you delete a layer and then
attempt to draw a new item.

(56) Bug Fix (11/28/04/JPR): Lithologic
profiles and fence panels no longer generate an error message if there are
undefined nodes within the model. This was a bug that was introduced in
the previous release.

(55) New Feature (11/25/04/JPR): A new program
called "Spider Map" has been added to the Geological-Utilities / Map /
Multivariate Maps sub-menu.

This program is used to display special "spider" diagrams that
depict the relative concentrations of up to nine mapped variables as polygons.

The Spider Map program menu is very similar to the other
Multivariate Map options.

Diagram Radii: Maximum radius (as a percentage of
the map size) of each sample symbol.

Scaling: Method used to define how variables are
scaled.

Automatic: Automatically scale all variables such
that the maximum value corresponds to the diagram radius. Note: When
this setting is used, the "Maximum Value" settings within each component submenu
is ignored.

Manual: This will use the "Maximum Value" settings
with the individual component submenus to define the scaling.

Fill Polygons: File all polygons with a
user-defined color.

Color: Color to be used when filling polygons.

Plot Polygon Perimeters: Plot a line around the
border of the polygons.

Line Style: Line style, color, and thickness to be
used when plotting a border around the polygons.

Offset: Distance from the maximum radius to the
start of the axis label.

Border: Plot annotated border around the perimeter
of the map.

Numerous settings identical to other programs that include a
Border option.

Symbol Index: Plot an index to the symbol (e.g.
component titles) along the right side of the map.

X-Offset: Horizontal (x) distance from the right
edge of the map to the origin of the index symbol.

Y-Offset: Vertical (y) distance from the top of the
map to the origin of the index symbol.

(54) New Feature (11/24/04/JPR): A new block of
menu items titled "Explode" has been added to the Geological-Utilities / Grid /
Grids -> Stratigraphic Model menu. If selected, the stratigraphic units
will be separated by either a uniform vertical distance or variable distances as
defined by a new "offset" column within the datasheet.

The "Uniform Spacing" option will vertical separate each
stratigraphic unit by the distance specified within the associated "Separation
Distance" setting as shown by the following example.

The "Variable Spacing" setting will separate each unit by the
amount specified within the "Offset Column" of the datasheet. This
new Offset Column and it's effects are illustrated within the following
examples;

Note: The z-coordinates within the "Cage" option are not
be applicable for exploded stratigraphy diagrams.

(53) Improvement (11/22/04/MMM):
The following menu items now "trigger" help messages along the right side of the
screen;

Borehole-Manager /
I-Data / Statistics

Borehole-Manager /
I-Data / Histogram

Borehole-Manager /
P-Data / Statistics

Borehole-Manager /
P-Data / Histogram

Geological-Utilities / Grid / Grid-Profile

Geological-Utilities / Grid / Grid-Fence

(52) Bug Fix (11/22/04/JPR):
The "lithoblending" now works correctly with data sets that are comprised of
very shallow boreholes separated by large distances (note how shallow the
boreholes are within the example below). Specifically, the program now
extends the lithologies to the extent of the project area.

(51) Bug Fix (11/22/04/JPR):
The "Distance Filter" option within the Borehole-Manager / I-Data / Volumetrics
program now works correctly. The previous version would zero the points
within the search radius rather than outside of the search radius.

(50) Bug Fix (11/22/04/MIW):
The RockPlot/3D IsoSurface now updates the Volume and the display after typing
in an IsoLevel and removing focus from the edit box or hitting enter.

(49) Bug Fix (11/22/04/JPR): The
Geological-Utilities column titles are no longer trashed after the Configure
option has been selected.

(48) New Feature (11/19/04/JPR): The
Geological-Utilities / Map / Starburst-Map program now includes an option for
plotting a symbol index.

The offset units refer to the position for the center of the
index symbol;

This option is especially useful when plotting unlabeled symbols
(i.e. maps that would be too cluttered with individual labels).

(47) New Feature (11/19/04/JPR): The
Geological-Utilities / Map / Starburst-Map program now includes an option for
plotting an annotated map border.

(46) New Feature (11/19/04/JPR): The
Geological-Utilities / Map / Starburst-Map program now includes an option for
specifying the amount of offset for the symbol annotation relative to the center
of the symbol.

This new feature is useful for eliminating label overplots when
working with symbols that contain many (e.g. 9) verbose labels.

(45) New Feature (11/19/04/JPR): The
Geological-Utilities / Map / Starburst-Map program now includes an automatic
scaling option that will scan the data and normalize the components to a
user-specified diagram radius. This eliminates the need to specify
individual scaling factors thereby making the program much easier to use.

Specifically, the user need only specify the input columns and
the maximum radius. There's no longer any need to know the range of the
data, the map dimensions, etc.

Map based on Surface_Geochemistry.atd sample file.

(44) Improvement (11/19/04/JPR): The
Geological-Utilities / Map / Starburst-Map program will no longer labels a
"petal" if the corresponding value for that petal is zero. This removes
unnecessary and obnoxious labels from the symbol labels.

(43) Bug Fix (11/12/04/JPR): Patterns are no longer
copied to the lithology or stratigraphy tables if the user selects the "Cancel"
option from within the pattern-selection window.

(42) Bug Fix (11/12/04/JPR): The Stratigraphy / Section /
Straight program now works correctly. The previous version would not work
unless the user had first performed another operation that recompiled the logs.

(41) New Feature (11/09/04/JPR): New bitmaps have been
added to the sample folder to illustrate the inclusion of bitmaps (raster
images) within borehole diagrams. Accordingly, the contents of BH01, BH03,
BH04, and BH06 have been changed in order to illustrate these capabilities;

(40) Bug Fix (11/09/04/JPR): The inclusion of bitmaps
within striplogs now properly offsets the logs if a header and/or footer offset
is specified within the bitmap table.

(39) Tip (11/04/04/JPR): If you're generating a very
large model, or anything else that takes a long time, and you can't tell if the
program is hung-up or not, open the \My
Documents\RockWorks2004\System\RW2004_log.txt file with a text editor. The
execution steps are listed within this file. Reload the file periodically
to check on the progress of the operation.

(38) Improvement (11/04/04/JPR): The following changes
have been made to the "lithoblending" modeling algorithm;

The interpolation of "outlier" nodes is now slightly faster.

The program will no longer interpolate points below the lowest
defined layer. By "defined", we mean a layer that contains at least one
control point.

The program will no longer interpolate points above the highest
defined layer.

(37) Cosmetic (11/03/04/JPR): The menu settings for 3D
fonts no longer include font angles because they were never used by any of the
programs (i.e. RockPlot/3D can only plot horizontal text).

(36) New Feature (11/01/04/JPR): It is now possible to
resample data within the I-Data and P-Data columns by right-clicking within the
appropriate datasheet and selecting the Columns / Resample option.

Examples:

Two-dimensional bargraphs of resampled I-Data:

Three-dimensional bargraphs of resampled I-Data:

Two-dimensional bargraphs of resampled P-Data:

Three-dimensional bargraphs of resampled P-Data:

(35) Cosmetic (11/01/04/JPR): The diagram cartoons
have been restored to the Geological-Utilities / Util / Geometry and
Trigonometry menus.

(34) New Feature (10/30/04/JPR): It is now possible
to specify the line thickness within graphic patterns.

This capability is especially useful for enhancing single-dot
patterns (e.g. sandstone) that may not be otherwise visible on higher resolution
devices (e.g. printers), as shown by the following example;

Compare Aquifer-1 and Aquitard-1 patterns within the two cross-sections.

Implications For Other Programs ("Ripple Effects"):

The Excel (XLS) import and export programs now expect and
include the pattern line thickness within the appropriate sheets.

The ASCII import and export programs now expect and include the
pattern line thicknesses..

(34) New Feature (10/31/04/JPR): The striplog
bargraph menu has been significantly modified;

The "Fill Style" and "Shape" options have been relocated into
separate 2D and 3D option menus to help eliminate some of the confusion between
the different types of diagrams.

The 2D fill styles have been simplified into four categories
while the pattern style has a new "white background" option (see diagram
below)..

The 2D border line style may now be adjusted (see diagram
below).

There is no longer a "None" option for the 3D fill style.

(32) New Feature (10/29/04/JPR): The lithoblending
algorithm now ignores control points that are outside the region that is defined
within the "Stratabound" filtering (assuming that the user has selected the
"Ignore" option within the Stratabound filtering menus). The following
example shows the results of separate stratabound filtering when combined with
the new Tilt feature;

(31) Bug Fix (10/29/04/JPR): When an RCL script is
launched as a Windows file association or from another program, the program now
displays the proper column titles within the Geological Utilities datasheet.
This bug did not effect RCL scripts that were launched from within RockWorks.

(30) Improvement (10/27/04/JPR): It is now possible
to specify the color and the radius of the log axis within three-dimensional
striplogs.

(29) New Feature (10/27/04/JPR): A new option
titled "Tilted Modeling" has been added to the solid-modeling options.
This feature will bias the lithologic modeling in a user-defined direction.

This new feature works like this;

The control point elevations are vertically shifted, based on
the orientation of the user-defined plane.

The solid model is interpolated (based on the vertically shifted
coordinates).

The corresponding nodes within the model are then shifted back
to their proper elevations based on the corresponding elevations within the
user-defined plane.

Why? Algorithms such as the horizontal lithoblending
strongly bias the interpolation in a horizontal fashion. The "tilt" option
introduces a regional gradient while still allowing the modeling to be horizontally
biased.

(28) New Feature (10/26/04/JPR): A new option
titled "Initialize" has been added to the The Geological-Utilities / Grid Menu.

This program can be used to create a new grid model that
represents a flat plane with a user-defined elevation or a dipping plane based
on a user defined orientation. If the plane is dipping, the user may
define the xyz coordinates for a point that the dipping plane will intersect.

Menu Options:

Grid Name: Name of grid model to be created.

Model Dimensions: Click here to set the dimensions
of the grid model.

Orientation: The new grid model may be either a
horizontal or inclined plane.

Horizontal: Set all nodes such that grid represents a
horizontal plane.

The following example depicts various dip dip directions with a
constant dip angle of -15 degrees.

Example: Let's say that a strike and dip on the surface was measured for
an important fracture orientation. The xyz coordinates for this point
would be used as the reference point for an inclined plane. By plotting
this plane in conjunction with other data (e.g. a stratigraphic block model),
the viewer can see where the plane should intersect other features (assuming, of
course, that fractures are perfect planes - which they aren't).

To isolate the exact intersection of two grid models, simply subtract one from
the other (via the Grid-Math routines). Node values that approximate zero
within the resultant grid model show where the surfaces intersect. In the
following example, the fracture plane surface (as generated by the new Grid /
Initialize program) was subtracted from the Aquifer-1 (baby-blue in the diagram
above) superface grid to create an intersection model. This grid was then
converted to a boolean grid as shown within the following grid.

Region where surface fracture intersects Aquifer-1.

(27) Improvement (10/26/04/JPR): The
Geological-Utilities / Util / Trigonometry / Apparent-Dip program now computes
the proper apparent dip angle when the dip direction is greater than 90 degrees.
The program now also uses the same dip angle convention as other programs within
RockWorks (i.e. 0 = horizontal, -90 = straight down, 90 = straight up).

(26) Improvement (10/25/04/JPR): The Grafix /
3D-Utilities / Oriented-Object program has been extended as follows;

An optional "Length" column may now be included within the input
file.

The oriented samples are now plotted as three-dimensional arrows
rather than elongated cones.

The xyz location for the sample now corresponds to the start of
the arrow rather than the midpoint.

A slew of new options have been added to the menu;

The new menu options are described as follows;

Length: The length of the arrow can be either
constant, or variable, depending upon the "Length" column.

Fixed: All arrows will have the same length.

Length: Fixed length of arrows as a
percentage of the overall project dimensions.

Variable: Arrow length will be defined by
the Length column within the input file.

Multiplier: Lengths will be multiplied
by this number to define the arrow length.

Color: Colors may be either fixed, defined by
the Color column within the input file, or automatically computed by
scanning the range of data within the Length column.

Fixed: All arrows will have the same color.

Color: Color to be used for all arrows.

Variable: Arrows will have different colors
based on either the Color or the Length column within the input file.

Automatic: Automatically color the arrows
by scanning the range of Lengths whereby low magnitudes are assigned
a "cold" color (e.g. dark purple) and the high values are assigned a
"hot" color (e.g. red).

Manual (Column-Based): Assign colors based
on the Color column within the input file.

Tube Radius: Radius (expressed as a percentage
of the project size) of the tube portion of an arrow.

Cone Radius: Radius (expressed as a percentage
of the project size) of the cone tip that is plotted at the end of an
arrow.

Cone Height: Distance (expressed as a
percentage of the project size) from the base of the cone tip to the end of
the arrow.

X-Offset: X-distance from the arrow start to the
label start.

Y-Offset: Y-distance from the arrow start to the
label start.

Z-Offset: Z-distance from the arrow start to the
label start.

(25) Improvement (10/22/04/JPR): The File / Import
/ Into-Borehole-Manager / XLS program will now disable any imported boreholes
that have bad or missing data for the borehole easting, northing, elevation , or
total depth.

(24) Improvement (10/22/04/JPR): The File / Import
/ Into-Borehole-Manager / XLS program no longer requires that Excel sheets exist
for all entities. For example, you don't necessarily need to have a
Lithology sheet. The Location sheet, however, is the only required
sheet.

(23) Improvement (10/22/04/JPR): The following
changes have been made to the Project Dimensions menu;

A red text message will now appear below the block-model diagram
indicating an error condition within any of the input parameters including
undefined parameters and node spacings less than zero. The program no
longer generates annoying and cryptic error messages as the user is trying to
enter data.

If the menu dimensions are unresolved and the user attempts to
switch to another mode (e.g. the Borehole Manager or the Geological Utilities),
the program will present the user with a gentle reminder to fix the problem.

(22) Improvement (10/21/04/MIW): The vertical scale
factor within the RockPlot/3D program no longer changes the aspect ratio of
cones, tubes, oblates, and spheres. This means that diagrams look good
even when they're vertically exaggerated.

(21) New Feature (10/21/04/JPR): A new option
titled "Vectors" has been added to the Borehole Manager / Striplog menu.

This option will plot vectors (as defined within the new Vectors
data group - see item #20 below) in three dimensions as shown within the
following diagram that includes lithology and flow vectors.

Multi-log diagrams with vectors are used to depict within the
following types of applications;

Hydrogeology: Groundwater flow directions.

Stratigraphy: Sedimentary structure orientations.

Paleomagnetism: Magnetic field directions.

Oceanography: Current directions and magnitudes.

Geotechnical: Ground movement (e.g. dam site
deflection).

Menu Options;

Length: The length of the vector can be either
constant, or variable, depending upon the "Magnitude" column within the
Vectors data group.

Fixed: All vectors will have the same length.

Length: Fixed length of vectors as a
percentage of the overall project dimensions.

Variable: Vector length will be defined by
the Magnitude column within the Vectors data group.

Multiplier: Magnitudes will be multiplied
by this number to define the vector length.

Color: Colors may be either fixed, defined by
the Color column within the Vectors data group, or automatically computed by
scanning the range of Magnitudes.

Fixed: All vectors will have the same color.

Color: Color to be used for all vectors.

Variable: Vectors will have different colors
based on either the Color column within the Vectors data group or the
Magnitude of the vector.

Automatic: Automatically color the vectors
by scanning the range of Magnitudes whereby low magnitudes are assigned
a "cold" color (e.g. dark purple) and the high values are assigned a
"hot" color (e.g. red).

Manual (Column-Based): Assign colors based
on the Color column within the Vectors data group.

Tube Radius: Radius (expressed as a percentage
of the project size) of the tube portion of a vector arrow.

Cone Radius: Radius (expressed as a percentage
of the project size) of the cone tip that is plotted at the end of a vector
arrow.

Cone Height: Distance (expressed as a
percentage of the project size) from the base of the cone tip to the end of
the vector arrow.

(20) New Feature (10/21/04/JPR): A new data group
titled "Vectors" has been added to the Borehole Manager.

This new data group allows the user to enter directional data
such as groundwater flow directions, tiltmeter data, sonar data (current flow),
etc. The data fields within the Vector group are defined as follows;

Depth: The downhole distance from the top of the
hole to the vector origin.

Direction: Azimuth clockwise from North
(0-degrees).

Inclination: 0 = horizontal, 90 = straight up, -90
= straight down.

Color: Color that will be used by when plotting
vectors within 3D logs (see item #21).

Magnitude: Current flow rate or any other parameter
that is used to define the "strength" of the vector.

(19) New Feature (10/20/04/JPR): A new option
titled "Normal Distribution" has been added to the menu that is activated by
right-clicking within a datasheet. This program is identical to the
Geological-Utilities / Stats / Random / Normal-Distribution program except that
it may now be used within selected Borehole Manager datasheets (see table within
item #15).

(18) New Feature (10/20/04/JPR): A new option
titled "Completely Random" has been added to the menu that is activated by
right-clicking within a datasheet. This program is identical to the
Geological-Utilities / Stats / Random / Completely-Random program except that it
may now be used within selected Borehole Manager datasheets (see table within
item #15).

(17) New Feature (10/20/04/JPR): A new option
titled "Warp Model Based On Grid" has been added to the solid-modeling options.

This new feature works like this;

The control point elevations are vertically shifted, based on
the corresponding elevations within the reference grid.

The solid model is interpolated (based on the vertically shifted
coordinates).

The corresponding nodes within the model are then shifted back
to their proper elevations based on the corresponding elevations within the
reference grid.

Why? Algorithms such as the horizontal lithoblending
strongly bias the interpolation in a horizontal fashion. The "warp" option
introduces structure while still allowing the modeling to be horizontally
biased.

Unwarped and warped lithology models.

Unwarped and warped I-Data models based on inverse-distance anisotropic
modeling.

- Thanks to Mike Brondos for another
great idea. -

(16) Cosmetic (10/20/04/JPR): The following options
have been moved from the main Edit menu to the new datasheet button menu (see
item #110);

Cut-All

Copy-All

Columns

Rows

Digitize

Filter

Refresh

(15) New Feature (10/20/04/JPR): A new option
titled "Datasheet Buttons" has been added to the General Preferences menu.
If selected, a series of data-manipulation "speed buttons" will appear within
the Geology Utilities datasheet as well as the individual datasheets within the
Borehole Manager.

These buttons may be displayed as large buttons with labels, or
small buttons without labels;

The configuration options include a list of selected buttons. This allows
the user to define which buttons will be displayed at the top of the datasheet.

The "Menu..." button will display a list of additional options
which were formerly located within the Edit menu;

This menu will also appear if the right mouse button is clicked
within a given datasheet. This is especially useful if the datasheet
button display has been disabled.

The following table shows which options are available for the
various datasheets;
